Shingle cutter apparatus

A shingle cutter apparatus, comprising,

• a rigid base plate, wherein the base plate includes a planar top surface spaced from a planar bottom surface, and
• the base plate having a first end wall spaced from a second end wall, and
• a first side wall extending orthogonally between the first end wall and the second end wall, and
• a top surface recess coextensively directed along the first side wall orthogonally oriented between the first end wall and the second end wall, and
• a metallic anvil blade fixedly mounted within the recess, and
• an abutment wall coextensive with the second end wall orthogonally oriented relative to the first side wall projecting above the planar top surface, with a graduated fence plate coextensively oriented along the abutment wall coextensively therewith, and
• a cutter blade, with the cutter blade including a pivot axle orthogonally directed into the first side wall below the abutment wall, the cutter blade having a predetermined length, the anvil blade having a length equal to said predetermined length, and
• a handle mounted to the cutter blade spaced from the pivot axle, and
• a rear leg plate mounted to the plate bottom surface in adjacency to the second end wall, and
• a forward leg plate parallel to the rear leg plate mounted to the planar bottom surface in adjacency to the first end wall, and
• the fence plate includes a fence plate pivot axle orthogonally directed into the planar top surface in adjacency to the anvil blade, and the fence plate having a fence plate handle extending above and longitudinally of the fence plate for manual manipulation of the fence plate, and the base plate having a first lock bore, a second lock bore, a third lock bore, and a fourth lock bore, each spaced a predetermined radial spacing relative to the fence plate pivot axle in a semi-annular array extending from the abutment wall, and lock means cooperative with the first lock bore, the second lock bore, the third lock bore, and the fourth lock bore selectively for permitting selective orientation of the fence plate in a first position, a second position, a third position, and a fourth position, wherein the lock means in registration with the first lock bore, the second lock bore, the third lock bore, and the fourth lock bore respectively, and
• the lock means includes a support flange fixedly mounted to the fence plate extending above the fence plate, and a lock rod slidably directed through the support flange and orthogonally directed through the fence plate, with the lock rod including a lock rod head positioned above the support flange, and a lock rod spring positioned below the support flange, and a capture flange fixedly mounted to the lock rod below the support flange, with a lock rod spring captured between the support flange and the capture plate to bias the lock rod through the fence plate into selective registration within one of said first lock bore, second lock bore, third lock bore, or fourth lock bore selectively, and
• the forward leg plate includes a pivot axle rod directed therethrough, and a first leg plate pivotally mounted to the pivot axle rod, and a third plate pivotally mounted to the pivot axle rod, with the first leg plate including a first leg plate slot, the third leg plate including a third leg plate slot, and a second leg plate having a second leg plate slot pivotally mounted to the first leg plate, with a first lock fastener directed through the first leg plate slot and the second leg plate slot to selectively orient the first leg plate relative to the second leg plate, and a fourth leg plate having a fourth leg plate slot pivotally mounted to the third leg plate, with a second lock fastener directed through the third leg plate slot and the fourth leg plate slot to selectively adjust positioning of the third leg plate relative to the fourth leg plate.
